Wireless communication anti-interference system

Abstract

The invention relates to a wireless communication anti-interference system, which belongs to the technical field of voice signal processing devices in the field of communications. The wireless communication anti-interference system comprises an input interface module and an output interface module which are connected through signal transmission, and is characterized in that: a speech channel switching module is arranged between the input interface module and the output interface module in a connection mode; a noise prediction module is arranged at an output end of the input interface module connected with the speech channel switching module in a fit mode; the noise prediction module is in control connection with the speech channel switching module; and a voice enhancement module which is in transmission connection with the speech channel switching module is arranged on the speech channel switching module in a fit mode. The wireless communication anti-interference system has novel design and reasonable structure, and can enable all speech channels to achieve the optimum voice effect by using one voice enhancement module only through the combined use of the noise prediction module and the speech channel switching module; and moreover, compared with the prior art that each speech channel needs to be provided with a voice enhancement module, the wireless communication anti-interference system greatly simplifies the structure, and significantly reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of voice signal processing devices in the communication field, and in particular relates to a wireless communication anti-jamming system. Background technique [0002] In mobile communication, due to the convenient mobility of mobile terminals, the use environment of mobile terminals is very complicated, especially in various noise environments, such as various traffic noises, electromagnetic noises, natural noises, and noises in public environments. Sound and so on. These noises will have a great impact on the voice quality, and the call quality will be greatly reduced. At present, these noise processing technologies include noise elimination technology (NR-Noise Reduction), noise compensation technology (NC-Noise Compensation), automatic gain control (AGC-Automatic Gain Control), acoustic echo control (AEC-Acoustics EchoControl) and other key These technologies have mature algorithms and module devices. ...

AI Technical Summary

Problems solved by technology

The application of technologies such as NR, NC, AGC, and AEC all need to be processed by digital signal processor (DSP-Digital Signal Processor) technology. At present, the 6000 series DSP of T1 company is basically used, and the immediate problem is the device cost. will lead to a substantial increase in production costs

Simply based on the cost of components required by NR, NC, AGC and AEC, it will increase by 80-90%. Moreover, after processing a channel that is not affected by environmental noise, the voice quality will be reduced instead.
